The time period of oscillation of a magnet in a vibration magnetometer

1.	The time period of oscillation of a magnet in a vibration magnetometer is `1.5` seconds. The time period of oscillation of another of another magnet similar in size, shap and mass but having one-fourth magnetic moment than that of first magnet, oscillating at same place will beA. `0.75 sec`B. `1.5 sec`C. `3 sec`D. `6 sec`
Answer» Correct Answer - C `T prop 1/sqrt(M) impliesT_(1)/T_(2)=sqrt(M_(2)/M_(1))implies1.5/T_(2)=sqrt((M_(1)//4)/M_(1))=1/2` `implies T_(2)=3sec `
